Reading a file from resources not working in gitlab CI

问题

I am getting an error while running tests on gitlab CI using the command:

./gradlew clean test

I am using test containers to run my tests: https://www.testcontainers.org/modules/docker_compose/

Here is the code I am using to load the docker compose file which is at src/test/resources.

@ClassRule
public static DockerComposeContainer container = new DockerComposeContainer(new File(BaseServiceTest.class.getClassLoader().getResource("docker-compose.yml").getFile()));

It runs fine when I run locally, buy when running ci on gitlab, I get the following error:

{"timestamp":"2019-06-17T18:47:44.903Z","level":"ERROR","thread":"Test worker","logger":"docker[docker/compose:1.8.0]","message":"Log output from the failed container:\n.IOError: [Errno 2] No such file or directory: '/builds/xxxx/xxxx/xxxx-xxxx/src/test/resources/docker-compose.yml'\n","context":"default"}

Following is my gitlab-ci.yml file:

include:
  - project: 'xxxx/xxxx/sdlc'
    file: '/sdlc.yml'

variables:
  CONTAINER_NAME: xxxx-xxxx

test:
  stage: test
  image: registry.xxxx.com/xxxx-alpine-jdk8:v1_8_181
  script:
    - ls -la src/test/resources
    - ./gradlew clean test -i

In my script, I have ls -la src/test/resources and I can see the docker-compose.yml file when that script is run. Not sure why it is not available when running the code.

回答1:

Based on the Testcontainers docs here. DinD service is required for Testcontainers on Gitlab CI

Here an example:

# DinD service is required for Testcontainers
services:
  - docker:dind

variables:
  # Instruct Testcontainers to use the daemon of DinD.
  DOCKER_HOST: "tcp://docker:2375"
  # Improve performance with overlayfs.
  DOCKER_DRIVER: overlay2

test:
 image: gradle:5.0
 stage: test
 script: ./gradlew test
